    The vendor reported a directory traversal vulnerability when processing
    DCC SEND requests.
  
Impact :

    A remote, authenticated user could send a specially crafted DCC SEND
    request to overwrite arbitrary files with the privileges of the user
    running ZNC, and possibly cause the execution of arbitrary code e.g. by
    uploading a malicious ZNC module.
  
Workaround :

    There is no known workaround at this time."
